Raypak 85, 120 manual Making the GAS Connection, Gas Pipe Capacity for different pipe sizes

Page 22

MAKING THE GAS CONNECTION

DANGER: Only carry out work on gas conduits and fittings if you are licensed for such work.

-Determine proper size gas pipe for the installation using Table 3 and Table 4. Do not forget the pipe fitting losses and observe proper size of the fittings.

-Install the furnished 3/4” female gas cock on the gas connection (3/4” male on the boiler) (Fig. 13).

-Connect the gas pipe to the gas cock so that it is free from any strain.

CAUTION: The boiler and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psi (3.5 kPa).

NOTICE: When installing the gas supply connection, it must comply with local regulations or, if such regulations do not exist, with the National Fuel Gas Code, ANSI Z 223.1.

In Canada, the gas supply connection must comply with local regulations or, if such regulations do not exist, with CAN/CSA B149, Natural Gas and Propane Installation Code. A sediment trap must be provided upstream of the gas controls.
